To ZZZ w 7mm t may concern Be it known that I, WALTER P. .MURPHY,

a citizen of the United vStates, and a yresident of the city of NewYork, in the county 'of New York and State of NewYork, have inventedynew and useful lmprovementsin Car-Roofs, of specification.

This invention relatesy car roofsl of the type shown in (1C. MurphyPatent No;l 1,133,493, dated March V30,

1915, wherein the roof sheets are pivotally mounted near the ridge `onthe substructure and are yarranged between mullions or battens that aredisposedL crosswise ofthe ear7 the mullions and the `flanges of theadjacent sheets on opposite sides thereof being covered by seam covers.

The principal object ofthe present invention is to provide a simplearrangement which will permit a greater movement of the sheets at theeavesof the car than at the ridge when'the. car is thrown out of squarewithout danger ofthe sheets or seam' covers striking themullionsandrbecomingy damaged and without requiring sheets 'or seam Covers ofspecial shape. `Another ob-` ject is to provide an end construction forf the roof which will permit the end seam cover to shift to. accommodateitself' to the greater movement of theend sheet at the eaves end ofthecar than at the' ridge,

joint between` the end sheets andthe end seam cover.

The inif'ention consists' in the 'arrangement for obtaining' a greaterspace between the side margins of the sheets andthe mulg` lions at theeaves than at the ridge to permit a greater movement of said sheets at.

the eaves than at the ridge; and it further consists of the parts and inthe arrangements and combinations of after described and claimed.

`The side and ridge margins of the roof sheets are flanged up and turnedin and downforming hooked flanges 21 and 22. The side margins of theroot sheets adjacent to the mullions 13 are covered by transverse seamcovers 25. The transverse seam covers 25 are of an invertedchannelshape. These seam covers straddle the inullions 13 and the sidemargins of adjacent sheets and have flanges 26 which extend inwardly andupwardly from the lower side margins of said seam covers, said flanges.26 beingy adapted to interlock with the hooked flanges 2l formed on theside margins of the roof sheets. Theeaves ends 27 of the top portion ofthe transverse seam covers are bent down @ver the eaves ends of themullions 13 and then turned under the adjacent flanges 20 ot' .the root'sheets located on each side of the mullions. The top portions of thetransverse seam covers lap at the ridge (not shown)` and are perforatedto receive saddle bolts 29 of running board saddles 30.

Inverted channel shaped ridge seam c`ov ers 23, which are similar incross-section to the transverse seamcovers 25, straddle the ridgemargins ot each of the adjacent curved roof sheets, and have their lowermargins llanged inwardly and upwardly to form hooked flanges (not shown)which interlock with the hooked flanges 22 at the ridge margins of eachsheet.

The adjacent ends of the ridge seam covers 23 and the ridge ends of thetransverse seam covers are covered by the usual four way centerorfcorner caps 31, each of which has an opening in each ot its fourwalls to receive the ends of the ridge and transverse seam covers. Thecenter caps have center holes in their top walls through which thesaddlebolts 29 pass.

vRunning boards 34 are secured to runnhigr board saddles 30, which `reston the transverse seam covers 25 and are supported on the mullions 13arranged beneath said-seam covers, thusv permitting movement kin theside flanges thereof.

of the sheets and the transverse seam covers. The running board saddles30 are secured to the substructure by the saddle bolts 29 which Vextendthrough the roof sheathing and ridge pole.

The bosses 17 in the root sheets are held down on the bosses 16 in theanchor plate 15 by means of intermediate running board saddles or anchorsaddles 36, Vwhich have their under sides shaped'to tit the pitch ofthe, roof and provided with circularr recesses adapted to lit over the`b'osses 1T of the roof sheets. The anchor saddles 3G straddleV the ridgeseam covers and are se` cured to the substructure by bolts 38 whichextend downwardly through the tops of theY `ridge seam covers, anchorplates, rooi" sheathing Vand ridge pole.

rlie mullions 13 taper in width from the ridge portion of the rooftoward the eaves so that the space between the side margin of a sheetand the adj arent side face of the adjacent mullion increases toward theeaves. This arrangement permits a greater ,amount of movement of boththesheets andthe seamcovers at the eaves than at the ridge. Thus, when thecariframe is distorted, the sheets tend to turn on their pivots near theridge and accommodate themselves "to the distorted shapes oi the spacesbetween mullions; and their capacity for accommodating themselves tosuch distortion is increased by the greater clearance furnishedat theeaves by the tapering ofthe inullions. The taper of the mullions suchthat, when the distortion ofthe car approaches a maximum, there issubstantially no clearance between the mullion and the sheet throughoutthe length of the sheet so that thebody of the mullion, notwithstandingitstaper, is suilcient to prevent the seam cover from being crushed bythe trainandrigidly secured to the end of the car,

For this reason, the'end seam covers do not interlock with the adjacentside flanges 2l v 0iV the end sheets, but are merely turned downinsideof thepans of theend sheets and provided with base )flanges 40, whichrest on the body portions ot thesheets with- A special end corner cap 50is used to cover the ridge ends ofl the end seam covers 39 and theadjacent ends of the end ridge seam covers.
